2015 Mercedes-Benz A-Class 1.6L Petrol · B23 PTM

The most recent DVSA examination on 29 August 2026 initially resulted in a failure due to a fractured nearside front coil spring, classified as a Major defect, before the vehicle was presented again on the same date and recorded as a pass. That said, the advisory items carried over from the failure are still highly relevant: the rear brake discs are noted as worn, and both front tyres are recorded as worn close to the legal limit and on the edge. Looking back through the history, the 2025 test was entirely clean, but the 2024 examination returned the same pair of front tyre edge-wear advisories, and the 2021 test produced a Dangerous failure for a nearside front tyre bulge caused by structural separation. The recurrence of front tyre wear issues across multiple tests, combined with the sudden coil spring failure and brake disc wear advisory, suggests a maintenance trend that is best described as stable but with emerging wear concerns rather than a pattern of steady improvement. The recorded mileage of 101,331 miles on an eleven-year-old vehicle equates to an average of around 9,200 miles per year, which is broadly typical for a car of this age and segment and indicates reasonably consistent use rather than long periods of standing or extreme high-mileage driving. There is no evidence in the MOT record of large mileage gaps between tests, which is reassuring from a corrosion standpoint, as regular use tends to keep components such as brake discs, calipers and exhaust systems free from prolonged surface rust and seizing. However, at over 100,000 miles, the major mechanical assemblies on this A-Class, including the engine, transmission, clutch (if manual), turbocharger and suspension, will be approaching the upper end of their expected service life, and consumables such as timing chains, auxiliary drive belts, water pumps and suspension bushes should be considered as items likely to require attention in the near future. The annual mileage is sufficient that calendar-based degradation of fluids and rubber components is less of a concern than it would be on a low-mileage or stored vehicle. Given the advisory for rear brake disc wear, a prospective buyer should physically measure remaining disc thickness with a vernier gauge if possible, or at minimum have the discs and pads inspected on a ramp, as worn discs on a Mercedes of this age and mileage often require replacement in pairs along with new pads. Brake shudder under heavy pedal application, pulsing through the brake pedal, or grinding noises from the rear would suggest the discs have corroded or worn beyond safe limits. The fractured front coil spring is a significant safety item that should have been rectified before the pass was issued, and confirmation of a quality replacement spring, ideally replaced in axle pairs along with a check of the strut top mounts and front suspension bushes, should be obtained from the seller, as a single broken spring often points to general suspension fatigue across both sides. The recurring front tyre edge wear is also worth investigating, as it commonly indicates incorrect tracking, worn suspension bushes or ball joints, or perished anti-roll bar drop links, all of which are plausible on a car that has covered this sort of distance over mixed road surfaces. On a test drive, the buyer should listen for clonking or knocking from the front suspension over speed humps and uneven surfaces, which would suggest worn bushes, drop links or top mounts, and pay close attention to any pulling to one side under braking, which can point to a binding caliper or a seized brake hose. Steering response should be checked for vagueness or a knocking feeling through the rack, as electrical power steering racks on this generation of A-Class can develop play or leaks with age. The tyres themselves should be inspected not just for tread depth but also for sidewall cracking or perishing, as even relatively new rubber can degrade with age, and a check of the DOT date code on the sidewall is sensible to ensure they are not older than five or six years. Finally, given the mileage and age, it is prudent to verify the full service history, confirm the cambelt or timing chain service interval has been observed, check that all warning lights extinguish promptly on ignition, and ensure that the automatic transmission fluid (if applicable) has been changed at the manufacturer-recommended interval, as these are all significant cost items on this platform if they have been neglected.
